Mirror symmetry on K3 surfaces via Fourier-Mukai transform
No full text"In the paper under review the authors define an analogue of the relative Fourier-Mukai transform for a minimal K3 surface equipped with an elliptic fibration p: X --> P^1 which is assumed to have a section. The compactification of the dual fibration is the moduli space M of stable sheaves on X of pure dimension 1 and Chern character (0, μ, 0) where μ is the cohomology class of the fibres of p. In fact, one has a natural isomorphism of X and M. The authors also show that M is isomorphic to the compactified relative Jacobian J(X) of X --> P^1. Further, it is shown that the action of the Fourier transform on the cohomologies of X reproduces relative T-duality and provides an isomorphism
\psi: H^{1,1}(J(X) ,C)/Pic(J(X))\otimes C --> H^{1,1}(X,C)/Pic(X)\otimes C,
where the LHS [resp. RHS] can be interpreted as the tangent space to the space of deformations of algebraic structures on J(X) [resp. Kähler structures on X] preserving the Picard lattice. Thus, can be regarded as the tangent map to a mirror map at J(X)."

A Tripartite Post-Recession Rebalancing
No full textIn this latest Advance & Rutgers Report, entitled “A Tripartite Post-Recession Rebalancing,” Dean James W. Hughes and Professor Joseph J. Seneca deliver an incisive assessment of the current market conditions and obstacles in the path of our economic recovery. They offer a statistical cautionary tale that the private and public sector need to hear and acknowledge in order for the economy to make continued progress.This report was published as Issue Paper Number 7, November 2011, in Advance & Rutgers Report
Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
No full textFirst evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)
Magnetoexcitons Bound To Ionized-donor Impurities In Gaas/al Xga1-xas Quantum Wells
No full textThe binding energy of Wannier excitons bound to ionized-donor impurities, D, in GaAs/AlxGa1-xAs quantum-wells, is studied using the effective-mass approximation within a variational approach, as a function of the well width for different barrier heights and growth-direction applied magnetic fields. Our calculations are devoted to heavy-hole magnetoexcitons. As expected, we found that the binding energy of a heavy-hole exciton bound to a donor-ionized impurity increases with the Al concentration, as well as with the applied magnetic field. Otherwise, we found that it is higher than the corresponding for heavy-hole excitons without impurities reported by other authors. Moreover we found that the binding energy of the heavy-hole exciton bound to a donor-ionized impurity is higher (lower) for larger (smaller) quantum well width. Finally we found that our results are in very good agreement when we compare with experimental and theoretical reports.4318992Dingle, R., (1975) Festkrperprobleme, 15. , H.J. Queisser (Ed.)

The vanishing author in computer-generated works: a critical analysis of recent Australian case law
No full textAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals
